声学 声压法测定噪声源声功率级 反射面上方采用包络测量表面的简易法
Application Summary AI generated
This standard specifies a simplified survey method for determining the sound power level of noise sources by measuring sound pressure levels over a reflecting plane using an enveloping measurement surface. It is applied in industrial and environmental noise testing contexts, such as evaluating machinery, equipment, or appliances, where a quick, practical assessment of noise emission is needed without requiring a fully anechoic or reverberant room. The method is suitable for quality control, product comparison, and noise labeling in manufacturing and regulatory compliance settings.
